Square mug warmer

Description: This mug warmer/heating pad is perfect for those who want to take their time sipping on a hot beverage. We all know too well, when we are busy and forget to drink our tea or coffee and it goes cold. With this heating pad you can keep your beverage at drinking temperature for hours. Can heat glass, metal, ceramic, aluminum, feeding bottles and milk cartons. Heats up to 70 degrees celsius. Notes: 1. We don't recommend using a concave or thick bottom base cup. This will affect the heating temperature.  2. This is a cup warmer only. Not an electric kettle. It can not boil water. 3. Heating time can be between 25-35 minutes. Depending on the base thickness of your cup.
